Base64 File Downloader

Turn a data URI into a saved file.

Decoded size
Detected type

This free base64 file downloader turns a base64 string or a full data URI back into a real file you can save. It decodes the data, auto-detects the MIME type from the data URI prefix (or uses the type and file name you supply), and reports the decoded size. Useful for extracting inline images, PDFs or other assets embedded in code. Decoding happens entirely in your browser, so nothing you paste ever leaves your device.
